Michael found a nice way to correct vignetting of Navcams, as you know. But yesterday he found something thats still more amazing: Navcam IMGs that are called "MILPRAD Radiometrically-corrected RDR calibrated to absolute radiance
units, specific to archived datasets only" in the MER Analyst's Notebook!

Here an (large) example what one can do with it:

These MRDs are already corrected with a mask that was made on Earth from the MER Navcams before they started.

Yeah, that's very nice!
As you already said, the radiometrically calibrated images are just what we tried to achieve with our anti-vignetting efforts, and it's routinely done by the rover team. Unfortunately, these MRD images are only available up to sol 370 or so. So the recent images aren't. I will post something on the conversion of these '.img' images during the next couple of days.
They contain 12 bit data and are thus much better than the 8 bit jpegs. I've got another (partial) panorama to offer. It's from Sol 111, and, in my opinion, still one of the best MER images.
